My father told me that there used to be a forest near our town. But the farmer who owned the forest1trees every year until one year, there were no trees left.

One day, our teacher took us out and we had a2in the field where the forest used to be. While eating and drinking, we3about the beautiful forest we once had. One of my classmates comes from a tribe (部落) that lived in the west of our country. He told us what he thought about the change. "It makes me really4to learn that a forest has disappeared. My people have taught me to 5thinks even generations (七代人) in the future. That's to say, when we do something to the land, we should never6it. We must care about nature and leave it good enough for later generations. "

When we heard what he said, we kept7first. "Let's plant some trees!" said our teacher after a moment. "It will be a good 8!" So that's what we did. For the rest of the spring, we worked hard and we planted thousands of trees.

That was five years ago. Today, when I stand in that field which was once empty, I see9about as tall as I am. It's great to see how we've10the field. It taught us the power of thinking about the future.

When Sally was a child, she went to the city park with her mom on a sunny morning. She felt very unhappy. Her mom saw that and asked why. Sally told her mother that she felt so sorry to see so much rubbish on the ground.

Her mom looked around. There were pieces of paper, boxes, glass bottles and a lot of other rubbish everywhere." What can we do?" asked Sally sadly. "I'm sure you will think of something," said her mom.

As soon as Sally got home with her mom, she painted a picture of the park and wrote a sign in large black letter at the top of the picture. The sign said, "PLEASE KEEPOUR PARK CLEAN". Later, she took plenty of bags and went back to the park with her mom. Sally put up her picture on a big rubbish box.

The children at the park ran over to see what was going on. Sally handed each of them a bag. "Let's clean up this place," said Sally. Then they began to pick up the rubbish, talking and laughing. Soon, all the bags were full.

Then Sally's mom led them to put the rubbish into different kinds of rubbish boxes. When they looked at the clean park, they all had a strong feeling of satisfaction.

From then on, Sally has been. keeping doing the cleaning and sorting (分类)rubbish. More and more people joined her to play a part in environmental protection.

Happiness is important to everyone. Most people want to be happy, but few know how to find happiness. Here is a story to help you.

Once a bird lived unhappily. So it traveled far away to look for its happiness.

It flew and flew. Suddenly it saw a spider climbing up a wall. The spider fell off the wall halfway. But it kept climbing again and fell off again. Even so, the spider didn't give up. The little bird asked the spider in surprise." Why don't you have pain but happiness on your face though you fail again and again?" "Because I keep making my efforts. I'm happy," said the spider. Then the little bird saw it—happiness is a will in the heart.

The bird continued flying and saw a lame duck help a little duck who got lost to find the way back home. Although it was disabled, it had a smiling face. "I'm happy because I can help others," said the lame duck. So the bird saw it—happiness is love in the heart.

The bird went on flying and suddenly saw a little dying flower, whose face was full of smile. The bird didn't know the reason. So it asked the little flower, "You're going to die. Why are you still so happy?" "Because my dream will come true," said the little flower." What is your dream?" "To produce sweet fruit. "The little bird saw it—happiness is a hope in the heart.

So the little bird no more looked for happiness because it had seen the true happiness is not in the faraway place but in your own heart. You are the maker of your own happiness.

If you you certainly will succeed.
